Banjo (I believe) was last seen in the 1980's. I was my favourite chocolate bar! There is a Campaign called BringBanjochocolatebar on FB trying to get it back on our supermarket shelves!
I only recently discovered there used to be a toasted coconut Banjo (red wrapper) dark chocolate (gutted I never tried). The blue wrapper one was peanut (milk chocolate) this I did try and loved it. I wish Mars would re-issue it (like Cadbury's Wispa after a public demand).
